Yes, there are a few things there that need updating but only a couple people who can, so it doesn't make high priority often lol. But all of the correct requirements are listed in the group memberships when you go to apply

I want to host a co op. I'm going to need to mail in some paperwork in order to do this here?? I have the required feedback here and from my eBay page.

Unfortunately you don't have enough posts to meet the requirements

Host requirements: 3 months of membership here and two sources of positive feedback, plus 1000 posts for swap hosts and 2000 posts for co-op hosts. Upon applying, we will call to verify your phone number, and send a letter that must be sent back to verify your address (this is for hosts, only).
